3 shields i tested as best, you need a shield early on because it blocks so much damage and reflects *best shield ever*
It's also quite expensive.
1 bond x 7 creatures = 7
2 bonds x 7 creatures = 14
3 bonds x 7 creatures = 21
4 bonds x 7 creatures = 28
5 bonds x 7 creatures = 35
6 bonds x 7 creatures = 42
This is assuming you get that many bonds out. But I do understand that you want a heal deck rather than a rush deck.
Anyways, I calculated your deck's Quanta Index (c)* and it's approximately 8.6, which is a very high QI. This means that you are using way too much quanta with too little towers to balance it out. Given, the QI is used as a measuring stick for pillars and not towers, but your deck is still slow and short on quanta.
With my suggestions (-1 Jade Shield, -3 Feral Bond, -6 Cockatrice, +6 Giant Frog), your QI is a bearable 6.9. Add this to the facts that this deck is not meant for rushing and that you have towers, not pillars, makes for a fair improvement for a smaller, tighter deck that sets up much faster.
